Chicago’s largest running group plans to don the blue and yellow color scheme synonymous with the Boston Marathon in a show of support and solidarity with victims of last year’s bombings.

The colors will be on T-shirts given to runners in the Chicago Area Runners Association’s 10-mile lakefront run planned for April 19, two days before this year’s Boston Marathon on April 21. The association also is selling blue shoelaces for $10; proceeds will benefit bombing victims.

Two bombs exploded April 15, 2013, near the finish line in Boston, killing three people and injuring more than 250.

The anniversary will be personal for Wendy Jaehn, who heads CARA. Like dozens of other Chicagoans, she competed in the race but was not injured in the explosions. “The goal is to just be back out there running and cheering,” Jaehn said, noting that a sizable contingent of Chicagoans will return to Boston for the race.

Last year, Jaehn led a solidarity run along Chicago’s lakefront the day after the bombings and told a large crowd of runners: “We’re not quitting, we’re not going to do anything different that would show that we’re afraid. The right thing to do is to keep on doing what we’re doing and just know that our hearts and minds are with those in Boston.”
